I hope so I just ordered the fuel pump lol I thought the 255 or whatever it is, was too much overkill... My stock pump is about to die anyway, it's even starving my stock 5.0L LOL
If you don't plan on running an FMU then it will be fine. Most of the Walbro 190s internally by-pass at around 60 psi (not sure why).
I supported roughly 300 RWHP on an 88 LPH pump with a Boost-a-pump. At 17V it provided around 137 LPH while the 190 provides roughly 176 LPH at 12V. Both flow rates given here are for 40 psi.
Not needed at your level, but for the sake of adjustmentability<~~~ is that even a word? and future mods, if you are replacing it anyway, get the Kirban!
